Va. Beloshenko et al., PROPERTIES OF ULTRA-HIGH-MOLECULAR POLYETHYLENE AND RELATED POLYMERIZATION-FILLED COMPOSITES PRODUCED BY SOLID-STATE EXTRUSION, Acta polymerica, 48(5-6), 1997, pp. 181-187
The structural, shrinkage and mechanical characteristics were studied
of specimens of ultra-high-molecular polyethylene (UHMPE) and polymeri
zation-filled composites UHMPE-Al and UHMPE-bauxite produced by plunge
r extrusion of powder material. It is shown that the dependence of the
strain-stress characteristics of UHMPE and its composites on the extr
usion ratio varies considerably in the presence of a filler. Mechanism
s explaining the behavior of the polymer material under study are prop
osed.
